Two times I peeled in on a heavily fortified target shooting S-24s and was shredded twice by Shilka fire, there was also enemy Destroyer's (SA- 8 )in the harbor who I am pretty sure sunk a few missles into my Mig 21 as it was being torn to shreds by the Shilkas.
I took an SPS-141-100 and turned it on and dove in on the same target destroying it without even being touched. (I thought at first it was luck) but I did it multiple times. On the setup I had buttons 1, 2, 3, and 5 all flipped up
9 was down and 10 was in the middle position. (I think).
Now do I think its functioning correctly? No (keep in mind I don't know how its suppose to work either). But I do believe it helps. and in my case it worked GREAT I have big plans for future missions.
If I could figure out how it works then I will be come dangerous.
